Summary
The earth dam stands at 20 feet tall and has a storage capacity of 59 acre-feet. With a surface area of 6 acres and a drainage area of 1.04 square miles, the dam serves as a popular spot for outdoor enthusiasts looking to enjoy water activities in a picturesque setting.
Managed by the Mississippi Department of Environmental Quality, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, the dam does not have an Emergency Action Plan (EAP) in place, raising concerns about emergency preparedness in the event of a potential breach or natural disaster. The dam's uncontrolled spillway and lack of outlet gates may pose challenges in managing water levels during periods of heavy rainfall or flooding.
Overall, Ridgeway Man Lake Number 2 Dam offers a recreational oasis for visitors in Mississippi, but its risk assessment and emergency preparedness measures warrant closer attention to ensure the safety and security of both the dam structure and the surrounding community. As water resource and climate enthusiasts, it is important to advocate for proper maintenance and risk management strategies to protect this valuable water resource for current and future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
